Efficient Circular Lighting Solution

Osram's circular T5 technology allows for the design of extremely flat and compact ceiling or wall luminaires. By distributing light evenly in a 360-degree circular path, this lamp eliminates the dark spots often associated with linear lighting. It is particularly well-suited for professional settings that require consistent, high-quality light for prolonged periods.

• Shadow-Free Illumination: Circular shape ensures uniform light distribution across all surfaces.
• High Color Fidelity: CRI between 80..89 allows for accurate color representation in work environments.
• Slim T5 Design: 16mm tube diameter allows for modern, minimalist fixture designs.
• Economical Performance: Exceptional efficacy (lumens per watt) reduces operational costs in large buildings.
